If this is true, please add to the previous feature request instead of creating a new one.
For what it’s worth, code blocks are a core part of markdown, and Obsidian is fundamentally a markdown editor. In fact, if you set up Atom as a markdown editor, it would also recognize code blocks.
Obsidian actually extends code blocks to make them more useful for people who do not use code. See e.g., the use of Mermaid for making diagrams, or various plugins’ use of code blocks to instantiate their features (e.g., dataview).
If you never use code, you could consider restyling generic code blocks to do something useful for you. Some users use code blocks to write and represent poetry, for example.
